Study On Macrofungi Resources And Their Ecological Distribution In Shaanxi Huang Bai Yuan Nature Reserve

Macrofungi is one of crucial environmental bio-resources.It plays important roles in maintaining ecological blance, accerlerating material cycle and energy flow in ecosystem. Moreover, it is one of important components in an ecosystem. Macrofungi also provide raw material for food processing, medicine extracting and agricultural pharmacy refining. For Shaanxi Huangbaiyuan Nature Reserve, Macrofungi has been thought one of most important bio-resources. To study on macrofungi resources and their ecological distribution will provide data for Shaanxi Huangbaiyuan Nature Reserve Administrative Bureau and support their national nature reserve applying.We combine method of field investigation with indoor identification to determine species of macrofungi and their distribution.The result demonstrated as follows.(1)There are 191 species macrofungi in Shaanxi Huangbaiyuan Nature Reserve, belonging to 2 phylum,4 classes,10 orders,41 families and 102 genus.According their nutritional models, there are 12 species parasitic fungus, 140 saprobiotic species fungus, 43 species mycorrhizal fungus there.According their commercial values; there are 103 species edible fungus, 45 species medicinal mushrooms and 18 species toadstools there.(2)There are 103 species edible fungus there,such as Auricularia polytricha(Mont.)Sacc., Morchella esculenta (Linn.)Pers., Lentinus edodes, Lactarius hatsudake Tanake., Hericium erinaceus(Bull. ex Fries)Pers.and Boletus edulis Bull ex Fr., etc.They are about 53.9% of total macrofungi species in the reserve. There are 45 species medicinal mushrooms there and about 23.6% of total macrofungi species in the reserve. There are 18 species toadstools there and about 9.4% of total macrofungi species in the reserve.(3)In some places in Shaanxi Huangbaiyuan Nature Reserve, marcofungi is less for the humidity and worse air exchanging condition. In the deciduous broad-leaved and coniferous forest at common elevation, medium marcofungi species are more with a little large species.In the valley Savanna shrubs, bushes and deciduous broad-leaved forest, especially on coarse wood, numbers of marcofungi are most.
